This I invention appertains to" improvements in pumping apparatus generally,-and more particularlytotypes ofsuch apparatus usually-employed in pumping-fluids from 15 deep'wells, such asoil Wells and the'like.

, An object of the invention is to provide for an apparatus of the class set forth, which is of a comparatively simple and inexpensive, but durable and eflicient construction 10 and; arrangement of parts, and which will effectively facilitate thepumping operations from deep wells with a minimum of extraneous power applied to the apparatus for the purpose. 15 Another object ofth'e invention is t'ojprof vide' fOIuZL'Il apparatus or device as hereinbefore characterized, which embodies amovable weight mechanism mounted and'arranged for effecting the actual pumping ope erations. alone, or for cooperationwith a prime mover 'ofa minimum horse power for accomplishing such operationsin the efficient manner as aforesaid. I

A further object ofth'e invention is to provide for a pumping apparatus orrn'eoha-nism of the character mentioned, which will be capable-of effectively and "efficiently pumping fluids from more than one' well at one 'and' the same time, and which embodies 30 means for counter balancing certain of the o erati-ve arts thereof when a um in o P V o eration is-bei'n g carried'out at one well only;

'lVith the foregoing andother equal-1y i-m portant objects'and advantages in view, the invention resides in the certain new andu'seful'combinations, constructions and" arrangements ofparts andmechanisms as willbe hereinaftermore fully described, set forth in the appended claims, and illustrated in 0 the accompanyingdrawings, i'n which:

Figure 5;is a perspective view of one of the "operativep'arts orpitmenof the power transmitting mechanism of {the apparatus, Figure .6 is a fragmentary front elevation of a second 'or' modifiedv form tus-,and s Figure' 7 is a vertical transverse section taken on-the line 77- of Figure 6. -Referring tothe' drawings, wherein like; characters of reference designate corresponding parts throughout the several views thereof, and more particularly to Figures 1 to5 inclusive, theembodiment of the in vention, as; shown therein by way of example, is constituted [in a main supporting frame consisting of three equi-distantly spacecland verticall y'disposed standards '10,

lland'" 12', wvhich are connected together attheir lower andnpper-en'ds by" means of horizontally disposedf mernber's or bars 13 Mounted on' a suitablesupporting base let atone side of the intermediateverticalframe member or standard 11 is a prime mover 15, which'may be any desired type of power generator, such as the interi ial combustion engine as shown; 'The 'power'transmitting shaft 16, of this prime mover 15, is journalledthrough the standard 1'1,-and"has ,a gear."elementwl7'kjeyed on itsfree end at the Arranged above-and in meshwith the gear element 17 is a second gear element 1 8, which is keyed 'or otherwise secured on the free end ofa shaft 19 journalled ina suitable support 20. Secured on the outer f'acefof the gear element 18, for rotation therewith, is: a sprocket 21, which is connected by a sprocket'ch'ai'n 22 to a second sprocket 23 keyed on the one-endof a shaft 24; journalled in the upper'end'of' a standard 25 rising from the suppo1't20. 'Toafford substantial bearing support/to the upper sprocket '23, an outwardly, bossedfbearing plate 26 is positioned between the hub portion of' the sprocket and the opposed face of the standard.25, and a fiat bearing plate 27' I similarlyfpositionedj between the opposite face of the 'stand'ard25 and a bearing collar 28 keyed 'on the end of the shaftfl opposite to that end on which. the" sprocket 23 is of'the' appara- 5b secured. These bearing plates 26 and 27 are secured to the standard 25 by means of bolts or the like 29.

Eccentrically secured to a common pivot 30 projecting outwardly of the front face of the upper sprocket 23, are a pair of oppositely directed pitmen 31, which have their outer ends separately pivoted, as at 32, to a horizontally disposed connecting member or bar 33. Secured on the front face of this connecting member or bar 33, and at the center thereof, is a pivot member 34, which is engaged by the upper end of a pendulum arm or rod 35. This member or rod 35 is mounted for oscillating or swinging movements on a pivot member orpin 36 projecting outwardly from a supporting plate 37 secured at the front side ofthe intermediate vertical frame member or standard 11. The lower and longer end portion of this member or rod 35 is preferably screwthreaded for a distance upwardly of its extreme free end to receive a follower or nut 38 thereon, upon which a weight 39 is adjustably supported.

The opposite ends of the connecting member or bar 33, beyond the pivot connection 32 of the pitmen 31 therewith, are, in turn, pivotally connected, as at 40, to the vertically directed arms of a pair of bell crank levers or the like 41, which are likewise pivoted, as at 42, at their angled connected portions, one to the front face of the upper end portions of the vertical frame members or standards 10 and 12. V In the use of the apparatus or device, as thus provided, one or both of the bell crank levers 41 are to have their lower and outwardly directed arm portions each pivotally connected, asat 43, to the upperend of a ump rod extension 44, which, in turn, will ave its lower end pivoted, as at 45, directly to the upper endof a pump rod 46. The pump rod 46 is, however, and preferably so, passed upwardly from the pump or well casing 47, and through guide membersor eyes 48 secured to the outer sideface of the standard. \Vhen one pump 47 only is to be operatively coupled to a rocker arm or bell crank lever 41, as shown in Figure 1, a rod 49 will be attached to the pivot connection 43 of the lower arm of the other of the rocker arms or bell crank levers to suspend an adjustable weight 50 therefrom to counterweight or balance the weight of the load of the pump rod 46 and other movable parts (not shown) of the usual pump equipment, connected to the rocker arm or lever at the opposite side of the frame. This weight 50 is preferably engaged on the lower end portion ofthe rod 49 for vertical sliding adjustments thereon, and is supported in any desired position of adjustment ona follower or nut 51 threaded on the extreme lower end of the rod for the purpose.

In the'operation of this form of the ap paratus or device, andv with the same installed in position at one side of a well, and the rocker arm or hell crank lever 41, at the near side thereof, operatively connected through the extension rod 44 to the pump rod 46 of the pump 47, the prime mover 15 will be started up, when power from the same will be transmitted through the intermeshed reducing gears 17 and 18, and from the gear 18 by way of the sprocket 21 rotatable therewith and the chain 22 to the upper sprocket 23. Assuming the power applied to the sprocket 23 to rotate the same in a clockwise direction, and with the parts of the mechanism initially positioned as shown, the pitmen 31 will impart a reciprocating movement to the connecting member or rod 33, which will, in turn, impart a rocking movement to the bell crank levers 41 on their fixed pivots 42, and, as a consequence whereof, a rectilinear motion will be imparted to the pump rod 46. With the initial reciprocating movement of the connecting member or rod 33, an oscillating movement will be imparted to the pendulum rod 35, which, under the impetus of the weight 39 will relieve the prime mover of a major portion of the working load. The elfectiveness of the working stroke of the pendulum rod 35 may be regulated to a nicety by adjusting the weight 39 on the lower end portion thereof, which may be readily accomplished by applying a wrench to the follower or nut 38. As'has been hereinbefore sug gested, a second pump may becoupled to the bell crank lever 41 at the opposite side of the frame, in which case, the counter-balancing weight 50 will be removed for the purpose. I

Referring now to Figures G and 7, the modified form of the apparatus shown therein contemplates the substitution of a simple form of weight motor for the prime mover 1.5 and its associated power transmission mechanism as constitutedin the reducing gears 17 and 18, and the lower and upper sprockets 21 and 23 and the chain 22 connecting the latter. v 7

In this instance of the invention, a gear element 152 will be secured on a shaft 153, which will be journalled in the upper end portion of thestandard 125 rising from the base 120. This gear element 152 will be located in the approximate position of the upper sprocket 23 of the first form of the device, and will have aneccentric connection 130 projecting from its front face to receive thereon the acent ends of the oppositely arranged pitmen 131, which are pivotally connected at their other ends, as

at 132, to the connecting member or rod 133.

Similarly, the opposite ends of the connecting member or rod 133 will each be pivotally connected, as at 140, to a rocking arm or hell igsassei at itscenter to the upright 'frame member 11'1'*of the main frame ofthe apparatus.

- The free endof the other orlower arm "of the rocking member or bell crank141 willbe pivotally connected, as at 145, to the pump rod extension 144, which ispivoted to the upper end of the pump rod, as in the first instance. I 1 p v s Rising from" the base 120 in spaced relation to'and in rear of the standard, or up right 125 is a second standard or upright 154, and jou'rnalled in the extreme upper ends of both standards or uprights 'in a shaft 155 on the intermediate portion of which'is a drum156." The front end of the shaft 155 is projected forwardly of the front standard 125, and is similarly journailed in the upper end of a standard or upright 157 arising from the upper end of the central or intermediate standard or upright 111 of the mainframe. Keyed-on the shaft 155 between the standard or upright 157 and the upper end portion of the standard 125 is a smaller gear element 158 which is meshed with the gear element 152. The foregoing apparatus constitutes the main power meansor prime mover ofth-is modified form ofthe invention, and thesame' is to be supplemented witha' secondary power means as follows Mounted on-the rear "end of the shaft 155beyond the rearface ofthe standard'154 is a gearfl element l'59,'which is meshed by a smaller gearelement 160 keyed ci-proeate the connect-ing. bar1'33; f Upon the onfthe shaft of a secondary; power device or electric motor 161. This power device or motor'161 is supported'fromthe standard 154 on a bracket 162. Normally wound on the drum 156 is a flexible cableor the like 163, which has one end fastened, thereto and its other end-free-to be attached toa weight 164.. Asshown, the base 120 is preferably formedfto provide anopen hollow vcenter so thatthe weight 164 will'have'an added travel downwardwithin the same-and thereby correspondingly increase'the time period of operating of the mechanism actuated by the unwinding of the cable. 163 underthe action of'thedescending weight. I i I In the operation of this'formof the apparatus or. device, and with the cable 163 wound upon the drum 156 and a pump rod connected to the extension 144 depending from a "rockerarmpr bellicrankj'lever 141 i at one side of the main frame, upon the re;-

lease of the drum" 156 for free rotation with its supporting shaft 155, the weight will descend between the standards 1 or uprights 125'and '154 and the cable 163 will. unwind from the drum and rotate the same; The power derived from the rotation of the drum 156 will-now be transmitted t0th6 reducing I gears 156 and 152 and-from the gear 152 to the pitmen 131, when the latterwill-reinitial reciprocation of the connecting bar 133', the weigh-ted pendulum bar- 135 will be oscillate'don its pivot'136by reason of the pivot connection 134 at its upper endtothe connecting bar 133; Thus the combined power from the drum 156 and the pendulum 135 will be transmitted by the connecting barv 133 toithe rockingarm ,Orbell crank lever 141 and the pump rod connection 144.

'When the weight 164" has reached the extreme limit of its downwardtravel at the bottom of the hollow center of .the base 120, the apparatus will stop, andthe power deviceor motor 161 willthus be started up e and throughthe" medium. of the m'eshing gears 160 and159 will rewindthecable 163 onto the drum 156 for-a subsequentor repeat operation of the pumping operation. I It is to be noted that in both forms of the invention, suitable brace members on the one hand, and 125" and 154, on.,the other hand, will'be employed in conjunction with the standards or uprights 25, 125 and 154, respectively, substantially as shown.
